This film largely features what Black Widow/ Natasha Romanoff was up to between the events of Captain America Civil War and Avengers Infinity War, but also has a bit of her back story and also post credits has a spoiler about Avengers Endgame.
It is a bit odd that this came out after Endgame, rather than in the correct chronological order and she doesn’t refer to the events in this film in Infitity War or Endgame making the film seem a bit pointless.
